The National Hurricane Center said Laura made landfall in southwestern Louisiana near Cameron around 1 a.m. August 27.
The governor of Louisiana says four people were killed by falling trees as Hurricane Laura moved through the state.
Governor John Bel Edwards said all of the deaths were caused when trees fell on their homes.
None were on the coast, having happened in Vernon, Jackson and Acadia parishes.
